Japanese electronics maker NEC has developed a CPU cooling system that is said to be 60 percent more energy efficient than a water-cooling system and 80 percent more efficient than an air-cooling system. The system relies mainly on a liquid chlorofluorocarbon (CFC) substitute to draw heat away from the processor core. The refrigerant boils at 122 degrees Fahrenheit, absorbs CPU heat, and is then cooled by a fan before changing back into liquid and repeating the process.
The system is also said to require less fan operation than other designs, and is said to be 70 percent cheaper ass well. The system was developed with the help of Japan's New Energy and Industrial Technology Development Organization.
Plans are in place to sell the system to data centers in 2011, where it should save them about 40 percent of total power consumption. A consumer version of the system has not been announced.
